What Causes Abrupt Diarrhea With Bright Green Stool?
shouldn't be
Detailed Answer:
Hi. Having abrupt onset diarrhea is relatively common, and the most common reason is an infection of the intestines, also commonly known as gastroenteritis. This infection is most commonly a virus (but sometimes can be a bacteria or a parasite). Viruses clear up on their own.
I would not think it's your gallbladder, unless you had it recently removed surgically. Otherwise you should not have diarrhea from your gallbladder itself. When it is gallbladder related, stools usually become very light, almost white, and stools "float" on the toiled, because of all the fat that was not absorbed by your intestines.
Give it a few days, if you don't get better, then seek medical attention for further testing.
Hope that helped. Let me know if you have further questions or concerns.
